W many pictures are there? i cant work with one number
Answer:
2y = 8
Step-by-step explanation:
4x+3y = 17
- ( 4x+y = 9)
----------------------
Distribute the minus sign
4x+3y = 17
- 4x -y =- 9
----------------------
0x +2y = 8
Answer:
- 32
- 400
Step-by-step explanation:
Lets start by defining the numbers in the equation.
This equation is in slope-intercept form meaning that it is y=mx+b or y = b+mx they are both the same
In slope-intercept form,
- m = slope or rate
- and b = y-intercept
Th equation is y=400+32x so now we know
For the first question the change per minute is the rate so it is <u>32.</u>
For the second question the starting amount is the same as the y-intercept so it is <u>400.</u>
Answer: 1900
Step-by-step explanation:
The answer is infinitely many solutions.
<span>x - y = 11
-x + y = -11
_____
Express the first equation in the term of x and substitute it into the second equation:
x = y + 11
</span>-x + y = -11
_______
-(y + 11) + y = -11
-y - 11 + y = -11
-y + y = 11 - 11
0 = 0
So, the system has infinitely many solutions.
